SODA-WATER-DRAFT APPARATUS.

SPECIFICATION forming part of Letters Patent No. 422,834, dated March 4,1890. Application filed November 22, 1889; fierial No. 331,218. (Nomodel.)

of reference marked thereon, which form a part of this specification.

This invention relates to soda-water-draft apparatus, particularly thatclass termed cabinet apparatus, in which a series of removablesirup-cans are employed. These cans are adapted to be drawn out for thepurpose of refilling or cleansing and subsequently returned to place.

My invention consists in improvements in the manner of mounting the cansto cause them to have easy sliding movement, likewise to prevent wearoccasioned by such movement when mounted in the ordinary way;furthermore, to provide easy engage ment of the can in its proper placeupon its return interiorly of the fountain; lastly, to enable the canto-be drawn nearly out and yet have it held in such position inengagement with the fountain during the act of refilling.

The drawings represent, in Figure 1, a front elevation in part of asoda-water-draft apparatus embodying my invention. Fig. 2 is a rearelevation of the same, the outer casing being removed. Fig. 3 is avertical section on line a: as, Fig. 1, transversely of the apparatus.Fig. 4: is a perspective view of a can bottom up. Fig. 5 is across'section showing a modification in the position of the guidebars.Fig. 6 is an improved sirup can under my invention.

In the drawings accompanying this specification, 2 represents theapparatus proper, provided with draft-cocks 3, one or more in number,and likewise with a series of contiguous sirup cans 4, which in a groupcombine to close an aperture 5 longitudinally along the front of theapparatus, and by means of which said cans are introduced within thecan-chamber. The latter is shown at 18, formed by a reversely-inclinedtop 6 and floor 7. The top (3 serves as the bottom of the ice-chamber 8,and inclines from the horizontal as it extends rearwardly, terminatingin a vertical plate 9, which is continuous the entire length of saidpartition 6. The lower edge of this plate is serrated, as shown in Fig.

2, andthereby serves to distribute the drip from the ice or coolingchamber from within in the form of water fro m the melting ice, fromwithout in the shape of water condensing upon the surface of the bottomof the chamber 6. Apassage 12 exists between the inner wall of thefountain and the distributer-plate 9 to allow the waste water to flowover said plate, and likewise to convey cool air into the can-chamber.The floor 7 of the latter is reversely inclined from the top, as beforepremised and as shown in Fig. 3. Upon this are fastened a series of ribsor guide-bars 13, which are intended to direct the cans in their properpaths and confine each one in the place provided for it.

In lieu of providing for the sliding movement of the cans after themanner of operating drawers, as likewise to economize material andsimplify the construction, I have mounted each can between twoguide-bars vertically aligned. Said bars extend from back to front ofthe fountain, the lower series 13, the upper one 14. The latter are ofless depth in the rear or taper (see Fig. 3) to offset the slope of thebottom of the chamber 6, from which they are pendent, and in order tomake both guides parallel. To secure the can upon such guide-bars, Ihave attached guides 15, Y-shaped in plan view, two below upon thecan-bottom and one above on the can-top. The bottom .ones are alignedwith each other and are coincident with the central longitudinal axis ofthe can, or thereabout. Thus each can is supported in aplane coincidentwith its center of body, and is consequently readily drawn in and out,While the parts employed in the mounting and guidance are reduced to thefewest possible and the construction is much simplified.

In Fig. i I have shown a can bottom up. In such drawing the can isprovided with. a reenforce or secondary plate 16, to which the guidesare securely bolted or soldered, preferably the latter. Said guides areplaced with the head of the Y facing the rear; hence in returning thecan to its proper place no trouble occurs in causing the guide-bars toenter such guides, since, even if the can is out of line when beingentered, it is at once brought into proper alignment by the convergingportion of the guide.

One advantage is apparent, and that is, that the cans may be pulled outa considerable distance and there beheld, such result being accomplishedby the position ofthe guides, as hereinbefore stated. Moreover, byattaching the guides to the can and having them engage the guide-bars,no wear of the can takes place, while the guides can readily be detachedand new ones substituted when Worn.

A11 evident alternative construction would be to secure the guide-barsupon the can and make the guides themselves stationary; but the methodshown in Fig. 2 is deemed preferable, owing to the aperture in the topof the can requisite for filling purposes. In connection with said canand its filling-aperture 19, I haveintroduced somenovelfeatures. (Shownin Fig. 6 of the drawings.)

What I desire to claim is- 1. In soda-water-draft apparatus, thecombination, with a removable sliding sirup-can,

of two parallel guide-bars arranged above and below said can inalignment with the central longitudinal axis of the latter and securedto the structure, and a number of guides attached to the can to engagesaid bars, substantially as herein specified.

2. The combination, with a soda-water-draft apparatus, the ice and canchambers, and a series of pendent guide-bars in parallelism within thecan-chamber, of a series of sirupcans, each provided with guides toengage two of the guide-bars, one in each series, substantially asstated and described.

. 3. In soda-water-draft apparatus, the combination, with a sirup-canapertured for filling purposes and provided with Y- guides above andbelow in the same vertical plane, of a pair of parallel guide-bars invertical alignment secured interiorly of said apparatus, and serving toengage the guides upon the can to permit free sliding movement of thelatter, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
